herokuにデプロイできません

お世話になっております。
現在、railsにて転職活動用のポートフォリオの作成に取り掛かって1ヶ月目なのですが、herokuにデプロイできず詰まっております。
初歩的な質問で大変恐縮なのですが、色々と調査をしてみたのですが原因がわからない為、同じ現象に遭遇したことがある方、もしくは何か原因に対してお心当たりのある方がいらっしゃいましたら解決方法に関してアドバイス頂けないでしょうか。

■解決したい課題
・herokuにpushしたい

■環境
・端末：MacBook Air (2020/13インチ)
・OS：macOS Catalina(10.15.7)
・シェル：zsh
・Ruby：2.6.6p146
・Rails：6.0.3.4
・ローカル環境：sqlite3
・本番環境：PostgreSQL

■参考にした記事
・【初心者向け】railsアプリをherokuを使って確実にデプロイする方法【決定版】

・GitHubとHerokuのデフォルトブランチをmasterからmainに変更してみた
https://zenn.dev/hiro_y/articles/b0839b76b9f1f58f7e17

■状況
【初心者向け】railsアプリをherokuを使って確実にデプロイする方法【決定版】サイトを参考にherokuへのデプロイ設定をしポートフォリオを作成しておりました。
初回とポートフォリオ作成初期段階まではpushできていたのですが、現在はpushに失敗してしまいます。

■試したこと
・作業ブランチがmasterであることを確認。
・bundle install --without production実行。
・git add -A → git commit ○○ → git push heroku master の抜けがないことを確認。
・heroku アプリ削除→再度作成しpush → 失敗
・違うブランチで作業しているよというエラーが発生 → git push heroku master:main → 失敗
・githubのデフォルトブランチをmain → masterに変更。
・heroku logs → Build failedが発生。build pack確認 → 何も入っていなかったので、heroku/nodejs、heroku/rubyをインストール。heroku buildpacksでインストールが成功していることを確認。
・heroku restart実行。
・【初心者向け】railsアプリをherokuを使って確実にデプロイする方法【決定版】を参考に再度確認
→bin/bundleファイルの先頭に #!/usr/bin/env ruby が存在していないことを確認。(このファイルは何も触っていません)
・GitHubとHerokuのデフォルトブランチをmasterからmainに変更してみたサイトを見つけ、開発途中アプリを消し、作り直しているので影響を受けたのでは？と考えデフォルトブランチをmainに変更。
git push heroku mainしたところ違うブランチで作業しているよというエラーが発生。
If you are developing on a branch and deploying via git you must run:git push heroku <branchname>:main
mainではないのブランチ直前のブランチ(herokuデプロイエラー用に作成していました)に移動しpush。下記エラーとなっております。

「rails app:update:bin」を実行し、コミットした場合、何か変化は見られますか?
